If you do not have oil in the RDU it will fail.
We need to address this issue!

Just a comment:
At 33K miles your power train is still under warranty. Basically the fluids are fluids for life and thus sealed units.
An axle should never need fluid unless there is a leak. A leak is the only way you will lose fluid, period.
In the old days I did have to check axle levels and transmission fluid levels on every oil change. These days you do not. In fact it is not advisable unless you see evidence of a leak.
In fact by just checking them you run the risk of introducing contaminants into the fluid and that would not be good. Overfilling is another risk.
In fact overfilling can cause over pressure and actually damage your RDU seals.
If you do not have oil/lube in the axle (RDU) or its low you have a leak.
If you have weep its very possibly you have a leak. You should not have weeping. A RDU does not use oil. the oil/lube may eventually wear out but does not evaporate as the unit is sealed.
I would not be buying/adding fluid as these are sealed units and are under warranty for at least 5 years and xxx miles.
The dealer needs to address the issue why you are losing fluid.
Adding that much fluid over time indicates a leak in the seals of the RDU.
Basically unless I saw evidence of a leak I would have absolutely no reason to even want to check the fluid level on a sealed unit.
Get it into the dealer pronto.
